Sm150t Soil Moisture Sensor - China

Research grade sensor

The SM150T’s advanced patented electronics and tough build produce a highly dependable sensor with exceptional salinity and temperature stability.

The SM150T is engineered to withstand long term burial – the sensor, connectors and cable are all environmentally protected to IP68 - It offers moisture accuracy of ± 3% (after soil specific calibration) and the built in temperature sensor achieves ± 0.5°C.
